To (tZZ wit-07271 it may concern:

Be it known that we, DANIEL D. WILEY, Gnonen L. XVILnY, and CHARLES W. WI EY, all of Lanark, in the county of Carroll and State of Illinois, have invented a new and Improved Windmill, of which the following is a full, clear, and exact description.

Our invention consists of improved contrivances for mount-ing the side vane so that it will turn more easily to enable it to be automatically shifted for varying the surface presented to the wind for a means of making the wheel automatically variable to the variations in the power of the wind for regulating the power of the wheel and for the protection of it from damage in powerful windgusts.

Our invention also consists of improved contrivances for so automatically shifting the side vane; and it also consists of improved contrivances whereby said side vane may be used as an automatic regulator to prevent the wheel from being suddenly thrust around with the shaft in geared mills when the load is suddenly turned on or clutched with the shaft, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a portion of our improved mill, showing the application for a bail-governor for regulating the side vane. Fig. 2 is a side View, and Fig. 3 is a plan view.

"We make the arm a, for the support of the side vane, b, and for the lever by which said side vane is to shift the wheel 0, to consist of a tube, which we mount rigidly on the turn table arm (1, that supports the shaft 6 of the wheel, extending said tubular arm about as far as the rear end of the side vane, b, and also extending said arm a on the other side of wheelsupporting arm (I, as represented in Fig. 3, in some cases, and we mount the vane b on this tube by a clip, f, near its front end, fitted .to turn freely on the tube, and by a rod. y, se

cured by a tie -head, It, to the vane near its rear end, and extending entirely through the tubular arm, in which it is fitted with bearingboxesv' for being supported substantially and so as to turn with the least amount of friction, and thus enabling it to turn so lightly that a ball-governor of ordinary capacity may be competent to shift it into and out of the wind for regulating the wheel, which would be entirely inefficient were the ordinary arm used and fitted to turn in a bearing of arm (1, and, beside, the arrangement for the support of the vane is much more substantial and durable. This vane 12 normally rests in the posi tion represented in Fig. 3-that is, edgewise to the windwhen the wheelcis working n01 mally-that is, when it is facing the windin which position it is held by the tail-vanej, and by the weighted cord usually employed to hold the wheel with its shaft in the line of the tail-vane; but when the wind blows'too hard for the wheel the vane b made to turn up sidewise to the wind more or less, to be forced around, thereby to swing the wheel around partially out of the wind to diminish the effect of the wheel.

In some cases we propose to employ a ballgovernor, 7t, for turning the vane, as represented in Fig. 1, the governor actuated by the variations in the speed of the wheel, as such governors are actuated when used f'oi'u'egulating the speed of steam and other engines; but we will in other cases utilize the wind for shifting the vane into the wind, and a spring for retaining the vane edgewise thereto, as represented in Fi 3, the area of the vane being greater on one side of the rod than the other. XVhen we use the governor, the tubular arm (6 will either terminate at the front side of the supportingarm d or will have a notch or slot to allow the crank l to be titted to the rod 9 thereat, and the shifting-rod m of the governor will be connected to said crank, the governor being geared by the pinion a on its driving-shaft with the toothed crank-disk 0 of the wind-wheel, or arranged in any other approved connection with the wind wheel shaft.

\Vhen the speed of the wind-wheel is normal, the vane will rest in the horizontal position represented by the dotted line b, Fig. 1; but with undue increase of speed the crank Z will be turned by the rising of the balls of the governor, shifting the vane more or less to ICC ward the line If, and thus presenting the surface of the vane to the wind proportionately to the force ofthe latter, by which the wheel will be turned more or less obliquely to the wind, the effect of which will be graduated on the wheel thereby.

\Vhen we use an unbalanced vane, b, to be turned into the wind by the greater effect of the wind on one side than on the other, we ar- 1 range a stop, 1), on the arm a, against which the vane comes to rest in its normal position, slightly inclined to the wind, as represented by the dotted lines I)", Fig. 2, with its widest side to windward, so that it will be turned up- 1 ward and sidewise tothe wind when the power of the wind is too great for the wheel. The arm a is also provided with a stop, q, to prevent the vane from being turned beyond the vertical plane.

2 For the spring to resist the wind and to return the vane b to the normal position, we em ploy a spring-rod, 8, connecting it to the crank Z at one end and to a supporting-arm, c, at the other end, said supporting-arm be- 2 ing attached to the tubular arm a, which in this arrangement is preferably extended forward of the wheel supporting arm d, but not nccessaril y so.

Vhen the wind-wheel is geared to a vertical 3O shaft, 10, by bevel-wheels my or any equivalent means, the wheel is often thrust around out of the wind to some extent when the shaft is momentarily slowed by the sudden increase of its load or resistance, as by the clutching on of another machine, and it always tends that way more or less by the resistance of the load.

This materially lessens the power of the machine, and especially at the moment when its utmost power is most needed, and its avoid- 4O ance is highly desirable, and may be effected by the use of this rotating side vane, b, which we propose to utilize therefor as follows: on the arm of the tail-vanej, by which the wheel 0 is always made to face the wind when at work, we arrange an arm, a, for the support of a stop, 0, in suitable proximity to crankpin d of crank Z to turn vane 1) into the wind whenever the wheel begins to swing by the stopping or slowing of the shaft, and thus ena- 5o ble the effect of the wind on the side vane to resist the turning of the wheel, the crank Z being in this case mounted at the extremity of the long extension of the arm (Z in front of the wheel-arm (Z, where the range of the arm will be sufficient to effect the necessary change of the vane b by a slight deflection of the wheel from its true position. The same spring 8 that is used to return the vanebto the normal position when used as a regulator of the Wheel to the power of the wind may be used in this case, and this device may also be employed where said vane is also employed'for such regulator.

In the use of this device for resisting the thrusts of the irregular load on the wheel we locate the stop-lug c of the wheel-armsupporting frame (1 so that when the wheel is in the normal position there will be sufficient space between said lug and the tail-vane-supporting framef to allow the wheel to turn the requisite amount for shifting the side vane, I),

by the stop 0 without contact of said lug c with said frame f, thus enabling the tail-vane to remain in its proper position by the thrusts of the wheel as it is in the common arrange ment of said lug close to the framef when the wheel is in line with the tail-vane, said lug being used in this as a safeguard against any undue shifting of the wheel in that direction for any cause. Its use in common mills is to keep the wheel from swinging. past the line of the tail-vane, for which it is necessarily arranged in contact with frame f, as above stated.

In order to cause the vane b to turn up vertically when the wheel is shifted around parallel with the tailvane,so as to present asym-' metrical appearance when the machine is at rest, we construct the crank Z with an arm, Z, extending in the opposite direction from shaft 0 g and connect a chain, 101-, to said arm, and to the end of stop-arm a, said chain being of such length that it will hang slack, as in Fig.

2, when the machine is at work, but will come taut and turn said vane when the wheel is 5 shifted around to the tail-vane as above stated.

The tail-vane is stayed by a trussrod, 0, suspended from the head of the pivot 9 of the wheel-supporting frame d,and the arm a may be stayed by a similar rod, q, but this rod [00 must be fitted to the pivot 12 so as to turn on it as the wheel-support shifts around.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is 105 1. The side vane of a wind-wheel, arranged to turn on the tubular supporting-arm a, and having a crank-shaft extending through said supporting-arm and acting by one of its crankpins upon a rod supporting a stop and 0011- necting with the vane-shaft, adapted to automatically shift said vane for regulating the wind-wheel, substantially as described.
